The processor 62 may initiate an activity automatically as a result of use of the electric toothbrush 35. For example, removal of the toothbrush 35 from its base 40 may initiate a communication between the base 40 and the display 45 to begin displaying information associated with an oral-care activity. Alternatively, energization of the toothbrush 35, or activation of a feature thereof, may cause the display of information on the display 45. A still further alternative permits a user to select and initiate an activity or display of information via a user interface, e.g., buttons 66 or screen 47 if the screen 47 is configured as a touch screen. The oral-care system 30 could also be configured to be responsive to voice commands to select and initiate the display of information.

The processor 62 may be configured to execute a set of instructions and/or a setup application. The setup application can be used to, for example, set a clock or calendar, to couple the oral-care system 30 to a network or other source of data and the like. The setup application may furthermore allow a user to select graphic themes and images, colors, sounds, messages and the like and to define multiple different users who might interact with the oral-care system 30 or the display 45, each possibly having a unique graphic theme or images, colors, sounds, etc.

The processor 62 may also be configured to execute a set of instructions associated with one or more analyses of personal care information that is input from sensors, the users, or the personal-care products. For instance, analyses of brushing times, oral-care regimens and/or habits might be performed (e.g., determining average brushing length, day or evening brushing habits, etc).

As previously discussed, the display 45 can be used with a suitable mounting structure to allow it to be mounted to a surface, such as a wall or mirror, or placed on a surface, such as a countertop. The surface may be horizontal, vertical or angled from vertical. In one embodiment, the sleeve 60 can be provided for slideably receiving the display 45, as shown for example in FIG. 3. The sleeve 60 can be mounted to the surface using adhesive, screws or any other suitable fastener known in the art. Additionally, the sleeve 60 might include a swiveling structure that is articulated to allow the display 45 and/or sleeve 60 to rotate, angle or extend toward a user. A ball and socket structure is one means that could be used to provide a swiveling motion. An alternative mounting arrangement illustrated in FIG. 5 includes an upstanding stand 70 upon which the display 45 is positioned. The display 45 may be secured to the stand 70 or may rest upon the stand without securing attachment. The stand 70 may provide for pivoting, rotating, articulating or other positioning motion to allow adjustment of the position and/or angle of the display 45 relative to the user.

Referring again to FIG. 3, the sleeve 60 has an opening 71 through which screen 47 of the display 45 can be viewed or accessed when the display 45 is received within, or attached to, the sleeve 60. The display 45 can be removed when necessary to replace one or more batteries (not shown) which can be used to power the display 45. The power source for the display 45 can be disposed within the housing 49 of a display 45. Buttons and/or switches 66 can be located on a rear surface 80 of the display 45 to control or enable one or more functions of the display 45 or to otherwise provide data input to the display 45. Alternatively, the buttons can be located on a front surface 85 of the display 45, on the sleeve 60 (which can be in electrical communication with the display 45), or the display 45 can incorporate a touch screen so that that data can be input directly using the screen. If the screen 47 is provided with touch sensitive capability, the screen 47 may display virtual buttons and selection features allowing user manipulation, control and option selection to be affected directly through the display 45. In some embodiments, data input to the display 45 or the sleeve 60 might control functions or operations of the electric toothbrush 35 (or another personal care product). For instance, a user might provide an input to the display 45 and/or the sleeve 60 that is transmitted to the base 40 and/or the electric toothbrush 35 to change the operation of the electric toothbrush 35. In other embodiments, buttons or switches 75 can be used to initially set parameters displayed by the display, such as the time and/or date for a clock or calendar that is displayed by the display 45.

In another example, a button or switch 66 might enable a night light function, wherein the screen 47, or a portion thereof, produces a low level light in the evening or overnight. The night light function might be governed by a clock or timer that is associated with the display 45, the base 40, or the electric toothbrush 35. The night light function might also be activated by detection of motion in the bathroom by a motion sensor located in the toothbrush 35, the base 40, the sleeve 60, or the display 45.

Referring to FIG. 7, in one embodiment, displayable information associated with one or more characteristics of the electric toothbrush 35 will now be described. An example of a pressure image 98 that can be displayed to signal high brushing pressure is shown in FIG. 7. A pressure sensor can be incorporated in the head 90, neck 95, or handle 100 of the electric toothbrush 35. An example of a pressure sensor suitable for use with the present invention is described in U.S. Pat. No. 7,120,960. The electric toothbrush 35 or the base 40 can transmit pressure data to the display 45. The display 45 can display the pressure data (or other oral-care or personal care information) as numeric, alpha-numeric, textual, images, or graphical information. Alternatively or in combination with the visual information, an audio signal might also be generated. For instance, an audible signal might alert a user that a certain brushing pressure has been exceeded.

Information associated with one or more brushing modes can also be displayed. For example, images 137 might indicate a basic cleaning mode; a soft brushing mode; a massaging mode; and a polishing mode. The operative brushing mode can be selected by user providing an input to the electric toothbrush 35, the base 40, the display 45, or the sleeve 60 via any user input device.

The electric charge of the electric toothbrush 35 and/or the display 45 can be represented by images 137 and 139, respectively, so that a user knows when a battery may need to be replaced or when the electric toothbrush 35 needs to be recharged. An image 141 can be also provided to indicate whether the display 45 is sending or receiving data. One or more images 153 might also be used to indicate when a component of the oral-care system, such as a brush head, needs to be replaced. Data could also be displayed that indicates the amount of useful life left for a component. For instance, the display might display a percentage of the useful life that is left for a brush head (e.g., 25% or 50% might be displayed). Other images or audio that might be produced by the display 45 include indications that a particular function of the toothbrush 35 has either begun or has terminated. For example, if the toothbrush 35 includes an LED, such as described in USPNs 2005/0053896; 2005/0053895; 2005/0053898; and 2005/00550659, the display might display an image that indicates the LED is either On or OFF, or the time remaining before it either turns On or turns Off. If the toothbrush dispenses a composition, such as described in U.S. Pat. No. 6,648,641, the display can display information about whether the toothbrush is dispensing or not dispensing a composition or an identification of what composition is being dispensed. An image 153 of the oral-care product (in this case an electric toothbrush) can be provided and portions 155 of the image 153 can be animated (e.g., blink or illuminate) to indicate that a particular function of the electric toothbrush 35 is active. In one embodiment, a logo 157 associated with the electric toothbrush 35 can be displayed.

Information that can be displayed on the display 45 that is associated with one or more characteristics of the oral-care regimen will now be described. Referring again to FIG. 7, the display 45 might display visual and/or audio signals to prompt a user to change the region of the mouth that the user is brushing. The entire dentition (teeth) schematically shown in the display 45 can be visually divided in any number of suitable segments. For example, the display 45 might display an image 105 representing one, two, three, four, and so on segments of the dentition. If desired, the entire dentition may be represented as a single section, or as two segments, one representing the upper (aka maxillary) teeth and the other representing the lower (aka mandibular) teeth (not shown). In another example, shown in FIG. 7, quadrants 110, 115, 120, and 125 represent the four quadrants of the maxillary and mandibular arches of the dentition. In one embodiment, each of the quadrants may successively blink and/or change color to indicate when it is time to move onto the next quadrant. In another embodiment (not shown in the drawings), the display may show six segments, representing, for example, upper front teeth, lower front teeth, upper right-side teeth, lower right-side teeth, upper left-side teeth, and lower left-side teeth. One skilled in the art would appreciate that other similar embodiments of the display's schematic representation of the user's mouth, having any suitable number of dentition segments, may be used, all of which are contemplated by the invention. A count-up or count-down timer 130 can also be included, wherein the display 45 displays the amount of time remaining in a brushing cycle. The brushing cycle time can either be pre-programmed or set by a user by inputting the time period to a component of the oral-care system 30.

Referring to FIG. 19, time is plotted on the abscissa, while the On and Off operating modes of the electric toothbrush are plotted on the ordinate. The time intervals shown on the abscissa of the timing chart are not to scale. At an instant of time 11, an electric motor and hence the electric toothbrush are turned on by a user actuating the On/Off switch. This On operating mode of the electric toothbrush is maintained for a first period T1 ending at an instant of time 12. The first period T1 thus represents a predetermined brushing time. On detecting the end of the first period T1, a timing circuit informs the user thereof by varying the mode of operation of the electric toothbrush. To this end, the timing circuit turns the electric motor and hence the electric toothbrush off and on again repeatedly by means of the On/Off switching device, thereby pulsing the head and the bristles. These actions of turning the electric toothbrush off and on are maintained by the timing circuit for the length of a second period T2 ending at an instant of time 13. This second period T2 represents the period in which the end of the first period T1, that is, the end of the predetermined brushing time, is signaled to the user by the repeated On and Off actions. This second period T2 is shorter than the first period T1.

The lengths of the On and Off intervals for which the electric toothbrush is turned on and off during the second period T2 are designated by T3. This period T3 is shorter than the second period T2, lasting between 0.3 and 1 second, for example. It will be understood that the On and Off intervals may also be of different lengths. The timing circuit detects the end of the second period T2, driving again the electric toothbrush into the On operating mode corresponding to the first period T1. In consequence, the On/Off switching device is closed. The user may then continue using the electric toothbrush and has the option of either turning the electric toothbrush off by means of the On/Off switch at an instant of time 14, as shown in FIG. 19, or continuing the use of the electric toothbrush until the expiration of the first period T1 is again signaled in the manner previously described.

At the completion of a brushing cycle, which can be conveyed by either the expiration of a time period of the timer 130 and/or an indication that brushing of the last quadrant of the oral cavity is complete (e.g., by illumination, blinking, or a color change of the image associated with the 4^(th) quadrant), a reward can be automatically displayed to the user to indicate successful completion of the brushing regimen. In one embodiment, a smiling face 135 can be displayed within the brushing quadrants to indicate completion of the brushing regimen. The reward can be helpful in promoting completion of the oral-care regimen. A reward can comprise visual and/or audio information that is intended to stimulate a desire to complete a particular task or regimen, or visual and/or audio information which a user finds desirable or pleasurable to view and/or hear upon completion of a task. The reward can be used to signal the completion of a task, or the completion of a task can be signaled by other visual and/or audio information. In some embodiments, the user can select or input (e.g., via the display 45) the type of the reward (e.g., image) that is displayed or audio that might be played. The reward can be displayed in a variety of ways and may or may not be associated with the image 105. In some embodiments, the reward can be provided as data stored with a personal care product (e.g., as part of memory 64 or an RFID tag, discussed below) and may be unique between personal-care products. One personal care product might store data associated with a first reward while a second personal care product stores data associated with a second, different reward. The reward could be associated with themes, slogans, colors, logos, icons, images, or other graphic or visuals that are uniquely associated with the personal care product, its packaging, or its marketing/advertising characteristics or messages. For instance, a child's toothbrush having a handle in the shape of a race care might contain data for a visual reward associated with car racing. Data for a plurality of rewards could be associated with a single personal care product so that different rewards could be displayed with each use of the toothbrush to refresh or maintain user interest or might be selectable by a user.

A plurality of either count-up and/or count-down timers might be displayed on the display 45. In some embodiments, 1, 2, 3, 4, or 5 timers might be provided. For instance, one timer might display the time associated with an overall oral-care regimen (e.g., how much time out of 2 minutes remains) while a second timer might display the time associated with one or more sub-regimens or toothbrush functions within the oral-care regimen (e.g., how much time remains for a light that illuminates the oral cavity to remain on during the regimen or how much time remains for the dispensing of a composition from the toothbrush). An example of such a display is shown in FIG. 8. One or more of the timers might be directly activated by a user of the display (e.g., as by a button on the display) rather than by data transmission between the display and the electric toothbrush.

In another embodiment, the display can interactively display questions and/or information associated with one or more characteristics of an oral-care regimen. For instance, the display might display one or more questions and one or more answers that can be selected by a user via a touch screen or buttons. The questions might be displayed at the beginning, during, or at the end of one or more oral-care or brushing regimens. The functional characteristics of the electric toothbrush 35 or information concerning the oral-care regimen might be automatically changed or adjusted depending on the answers to the one or more questions. For instance, a question might ask if the brushing experience was too hard or soft. Depending on the answer, the speed, frequency, or pressure sensor limit value (i.e., the value at which a warning is displayed that too much pressure has been applied) of the electric toothbrush might be automatically adjusted, or the amount of time displayed for the timer might be adjusted. The processor 62 could implement these changes in response to the input from the user. In another instance, the display might display information concerning alternate products or instructions concerning the use of the electric toothbrush 35 (or its accessories) that might provide an improved brushing experience. In another instance, the answer to one question might lead to a second question. For example, a question might ask whether the user was pleased with the brushing experience. An answer of “no” might lead to one or more follow up questions, such as did the user experience any tooth sensitivity. If the answer were “yes”, the processor 62 could implement one or more changes in the operation or characteristics of the electric toothbrush to reduce tooth sensitivity (e.g., altering the speed, frequency, amplitude of the brush head movements or altering the bristle configuration). The memory 64 can store the instructions and data associated with the questions, answers, and algorithms for the sequence of questions. These instructions and data can be periodically updated if the oral-care system is connected to a network.

Some information that can be displayed on the display 45 that is not related to the characteristics of the electric toothbrush 35, or characteristics of the oral-care regimen, will now be described. A coupon code (or equivalent) that can be redeemed for a coupon or discount (either via the Internet or in store) can be provided at a variety of times during use of the electric toothbrush 35. For example, a coupon code might be displayed after a predetermined period of brushing or when a component, such as a toothbrush head, should be replaced. The coupon code can be displayed when multiple products from the same manufacturer are used or when certain characteristics of an oral-care regimen have been fulfilled (e.g., completion of a predetermined number of brushing cycles that have lasted for a minimum period of time, such as 2 minutes). Other information, such as weather, music, news, sports scores, stock quotes, etc., can be streamed to the oral-care system for display on the display 45

Referring to FIG. 9, in another embodiment, the display 45 and/or the sleeve 60 can incorporate one or more light sources 155 to illuminate the oral cavity. Examples of light sources include light emitting diodes, laser diodes, flash lamps, and any other light or electromagnetic energy source. The light sources can be arranged in a variety of patterns on either the display 45 and/or the sleeve 60, including in a line, along an edge of the display 45, or any combination thereof. A diffuser or lens can be placed over the one or more light sources 155 to diffuse or focus the light as desired. The diffuser or lens can be adjustable so that the intensity and/or the size/shape of the light pattern can be varied depending on user preference. In another embodiment, the light intensity can be varied by altering the voltage and/or current to the one or more light sources 155, to increase or decrease the intensity. The voltage and/or current can be varied by a switch, button, or dial located on the display 45 and/or sleeve 60 that is in electrical communication with the one or more light sources 155.

In another embodiment, the one or more light sources 155 may be disposed on a device 157 having a stand 158 but which does not include the screen 47, as shown in FIG. 10. In this embodiment, the screen 47 might be replaced by a mirror 159 so that the light sources 155 illuminate the oral cavity and the mirror 159 of the device 157 can be used to view the oral cavity.

The device 157 can be provided in a variety of shapes and sizes. The device 157 and/or or the one or more lights sources can be configured to rotate or swivel so that a user can direct the light from the light sources in a manner that best illuminates the oral cavity, including hard and soft tissue like the teeth and gums. In one embodiment, a plurality of mirrors can be provided, wherein one of the mirrors magnifies the reflections from the oral cavity to improve the detailed viewing thereof.

In one embodiment, the one or more light sources 155 of the display 45 or the device 157 can be used with an oral-care composition, such as a dentifrice or rinse, that comprises a disclosing agent or a plurality of disclosing agents. The disclosing agent can be utilized to provide visual indication of one or more conditions of the oral cavity to an observer and/or user. As used herein, the phrase “conditions of the oral cavity” is used to refer to dental plaque, tartar, debris, tooth decay, bio films, soft tissue abnormalities, soft tissue lesions, etc. within the oral cavity. As used herein, the terms “plaque” and “dental plaque” are used to refer to a biofilm that builds up on teeth, on gingival tissue, oral hard tissue, and/or oral soft tissue. “Plaque bacteria” means bacteria that causes plaque to form.

The visual indication of oral conditions to the observer and/or user can assist the observer and/or user in removal of the conditions or in identifying conditions which should be treated by a professional, e.g. dentist, oral surgeon, etc. The disclosing agents may visually indicate a condition within the oral cavity by providing a visual contrast between the conditions of the oral cavity and other tissues and surfaces within the oral cavity. For example, a disclosing agent may be selected such that when the disclosing agent is subjected to energy from an energy source, such as the light sources 155 of the display 45, the disclosing agent fluoresces at locations of the oral conditions. Other examples of providing visual contrast are discussed hereafter. As a specific example, the disclosing agent may be applied to the oral cavity and visually highlight and/or indicate remaining plaque to a user and/or observer.

In some embodiments, any agents, materials, elements, compounds, or compositions, which will absorb light energy at a first range of wavelengths and, in response, emit light at second range of wavelengths can be a suitable disclosing agent, so long as it is safe for use in the manner intended here. In some embodiments, the first range of wavelengths may be different than the second range of wavelengths. For example, the disclosing agent may comprise a fluorophore.

Some examples of suitable disclosing agents include fluoroscein, dibromofluoroscein, tribromofluoroscein, tetrabromofluoroscein, other fluorescein derivatives (including salts thereof), xanthenes, pyrenes, e.g. pyranine, D&C Blue No. 1, D&C Blue No. 2, D&C Green No. 3, D&C Red No. 3, D&C Red No. 6, D&C Red No. 7, D&C Red No. 21, D&C Red No. 22, D&C Red No. 27, D&C Red No. 28, D&C Red No. 33, D&C Red No. 40, D&C Yellow No. 5, D&C Yellow No. 6, D&C Yellow No. 10, combinations thereof or any other dye approved for use in drugs and cosmetics by regulatory agencies such as, for example, The United States Food and Drug Administration. Other suitable disclosing agents may include dyes sold under the trade name Alexafluor™ by Invitrogen Corporation located in Carlsbad, Calif.

In embodiments where the disclosing agent comprises a fluorophore, the disclosing agent may be selected such that the disclosing agent fluoresces in response to electromagnetic energy from the light sources 155 having wavelengths which range from about 380 nm to about 780 nm, or any individual number within the range. In some embodiments, the disclosing agent may fluoresce in response to electromagnetic energy having wavelengths which are greater than about 380 nm, greater than about 390 nm, greater than about 400 nm, greater than about 410 nm, greater than about 420 nm, greater than about 430 nm, greater than about 440 nm, greater than about 450 nm, greater than about 460 nm, greater than about 470 nm, greater than about 480 nm, greater than about 490 nm, greater than about 500 nm, greater than about 510 nm, greater than about 520 nm, greater than about 530 nm, greater than about 540 nm, greater than about 550 nm, greater than about 560 nm, greater than about 570 nm, greater than about 580 nm, greater than about 590 nm, greater than about 600 nm, greater than about 610 nm, greater than about 620 nm, greater than about 630 nm, greater than about 640 nm, greater than about 650 nm, greater than about 660 nm, greater than about 670 nm, greater than about 680 nm, greater than about 690 nm, greater than about 700 nm, greater than about 710 nm, greater than about 720 nm, greater than about 730 nm, greater than about 740 nm, greater than about 750 nm, greater than about 760 nm and/or less than about 780 nm, less than about 770 nm, less than about 760 nm, less than about 750 nm, less than about 740 nm, less than about 730 nm, less than about 720 nm, less than about 710 nm, less than about 700 nm, less than about 690 nm, less than about 680 nm, less than about 670 nm, less than about 660 nm, less than about 650 nm, less than about 640 nm, less than about 630 nm, less than about 620 nm, less than about 610 nm, less than about 600 nm, less than about 590 nm, less than about 580 nm, less than about 570 nm, less than about 560 nm, less than about 550 nm, less than about 540 nm, less than about 530 nm, less than about 520 nm, less than about 510 nm, less than about 500 nm, less than about 490 nm, less than about 480 nm, less than about 470 nm, less than about 460 nm, less than about 450 nm, less than about 440 nm, less than about 430 nm, less than about 420 nm, less than about 410 nm, or less than about 400 nm.

In some embodiments, the disclosing agent may fluoresce in response to electromagnetic energy from the light sources 155 having wavelengths which are from about 400 nm to about 530 nm. For example, in one specific embodiment, the disclosing agent fluoresces in response to electromagnetic energy having a wavelength of about 470 nm. In other embodiments, the disclosing agent may fluoresce in response to electromagnetic energy having wavelengths between about 400 nm to about 440 nm. In other embodiments, the disclosing agent may fluoresce in response to electromagnetic energy having wavelengths between about 440 nm to about 530 nm. Additionally, embodiments are contemplated where the disclosing agent fluoresces in response to electromagnetic energy having wavelengths which are outside of the visible light spectrum, e.g. either higher or lower, combinations of higher and lower, and/or combinations of higher, lower, and visible spectrum. For example, embodiments are contemplated where the disclosing agent fluoresces in response to ultraviolet light, e.g. UVA about 315 nm to about 400 nm; UVB about 280 nm to about 315 nm; and/or UVC less than about 280 nm.

In some embodiments, the disclosing agent may emit electromagnetic energy having wavelengths of greater than about 400 nm. For example, disclosing agent useful in the present invention may emit electromagnetic energy having wavelengths which are greater than about 410 nm, greater than about 420 nm, greater than about 430 nm, greater than about 440 nm, greater than about 450 nm, greater than about 460 nm, greater than about 470 nm, greater than about 480 nm, greater than about 490 nm, greater than about 500 nm, greater than about 510 nm, greater than about 520 nm, greater than about 530 nm, greater than about 540 nm, greater than about 550 nm, greater than about 560 nm, greater than about 570 nm, greater than about 580 nm, greater than about 590 nm, greater than about 600 nm, greater than about 610 nm, greater than about 620 nm, greater than about 630 nm, greater than about 640 nm, greater than about 650 nm, greater than about 660 nm, greater than about 670 nm, greater than about 680 nm, greater than about 690 nm, greater than about 700 nm, greater than about 710 nm, greater than about 720 nm, greater than about 730 nm, greater than about 740 nm, greater than about 750 nm, greater than about 760 nm and/or less than about 800 nm, less than about 780 nm, less than about 770 nm, less than about 760 nm, less than about 750 nm, less than about 740 nm, less than about 730 nm, less than about 720 nm, less than about 710 nm, less than about 700 nm, less than about 690 nm, less than about 680 nm, less than about 670 nm, less than about 660 nm, less than about 650 nm, less than about 640 nm, less than about 630 nm, less than about 620 nm, less than about 610 nm, less than about 600 nm, less than about 590 nm, less than about 580 nm, less than about 570 nm, less than about 560 nm, less than about 550 nm, less than about 540 nm, less than about 530 nm, less than about 520 nm, less than about 510 nm, less than about 500 nm, less than about 490 nm, less than about 480 nm, less than about 470 nm, less than about 460 nm, less than about 450 nm, less than about 440 nm, less than about 430 nm, less than about 420 nm, or less than about 410 nm.

Referring to FIG. 12, the oral-care system 30 may further be adapted to communicate data between itself and a network 161, including local area networks (LANs), wide area networks (WANs), portions of the Internet such as a private Internet, a secure Internet, a value-added network, or a virtual private network. The oral-care system 30 can communicate with the network 161 by a data link 163, which can be a wireless or a signal line. Suitable network clients 165 may include personal computers, laptops, workstations, disconnectable mobile computers, mainframes, information appliances, personal digital assistants, and other handheld and/or embedded processing systems. The signal lines that support communications links to the network 161 and clients 165 may include twisted pair, coaxial, or optical fiber cables, telephone lines, satellites, microwave relays, modulated AC power lines, and other data transmission “wires” known to those of skill in the art. Further, signals may be transferred wirelessly through a wireless network or wireless LAN (WLAN) using any suitable wireless transmission protocol, such as the IEEE series of 802.11 standards. Although particular individual and network computer systems and components are shown, those of skill in the art will appreciate that the present invention also works with a variety of other networks and computers.

Referring to FIG. 13, the oral-care system 30, a plurality of oral-care products 170, 175, 180, and 183, and a non-oral-care personal care system 185 are illustrated. The oral-care product 170 is illustrated as a packaged oral-care rinse product; the oral-care product 175 is illustrated as a packaged dentifrice product, the oral-care product 180 is illustrated as a manual toothbrush product, the oral-care product 183 is illustrated as a packaged tooth whitening product (e.g., as disclosed in U.S. Pat. No. 5,891,453), and the personal care system 185 comprises an electric razor 187 that is received within a base 189. Examples of razors that are suitable for use with the present invention are disclosed in U.S. Pat Nos. 6,594,904; 6,442,839; 6,298,559; 6,295,734; 6,237,232; 6,216,349; 6,212,777; 6,041,926; 5,787,586; 6,192,586; 6,185,822; 6,052,903; 6,889,438; 6,029,354; 6,161,287; 2006/0200992; 2005/198842; 2006/0080837; 2006/0032054; 2006/0032055; 2006/0037107; and 2006/0032053. The oral-care products 170, 175, 180, and 183 can communicate using data links 191, 193, 195, and 196, respectively, with the display 45. The personal care system 185 can communicate via data link 197 with the display 45. While certain products have been shown for ease of discussion, it will be understood that a variety of products and personal care systems can be substituted. The data links can be wireless or via signal lines as previously discussed. The personal care system 185 and products 170, 175, 180, 183 may also be connected to a network as previously described. As will be appreciated, the present invention is suitable for use with products that comprise an internal power supply as well as products that do not, such as a packaged rinse product.

As previously discussed, the products and systems of the present invention can use a variety of methods and devices to store, transmit and/or communicate data between the systems/products and the display. The term “data” is intended to refer to any digital or analog information in any form that is transferred or communicated between two devices or components. Data may include any data actively transmitted by a data transmitter and/or data that is passively detected by a data reader. Data may include ones and zeroes if the data that is communicated is digital. In another embodiment, data could be a series of digits, such as 12345678, wherein each digit could represent information about a characteristic of an oral-care device (e.g., for a manual toothbrush, the first digit could represent the brushing time in minutes, the second digit could represent the number of months until the brush should be replaced, the third and fourth digits could represent a type unique reward, etc.). Data may include the arrangement of optical elements (e.g., a bar code) that represent information. Data may include the presence or absence of electromagnetic energy (e.g., such as a magnetic field) and the like. The data may be interpreted or decoded by the processor 62. For instance, where the data is a series of digits, such as 12345678, the processor 62 and/or associated memory could comprise a set of instructions that would be able to decode or interpret the data to determine what information is represented by the data.

A data transmitter is a device or component that actively transmits data to a data reader. An RFID tag is an example of a data transmitter. A data communicator is a device or component that may or may not actively transmit data but which has data that is capable of being detected. While a data transmitter, such as an RFID tag, is a type of date communicator, a data communicator need not necessarily actively transmit data. Examples of data communicators that contain data that that may be detected or read by a data reader but which do not actively transmit data include a bar code (wherein the bar code reader is the data reader), a spotcode, a non-contact photo-electric sensor, or a hall effect magnet (wherein the hall effect sensor is the data reader). One example of this would be a magnet in the personal care device and a hall-effect sensor or reed switch as the data reader. Thus, as will be appreciated, the phrases “data communicators,” “data transmitters,” and “data readers” are intended to encompass a wide variety of devices and arrangements for the transmission, communication, and/or detection of a variety of analog or digital data, including the mere detection of the presence of a data communicator. Examples of such devices include, without limitation, optical devices, magnetic and electromagnetic devices, bar codes, or any other devices capable of providing data communication as described herein. The phrase “data communication” is intended to encompass all the methods and forms by which data may be transmitted, communicated, and/or detected by a devices of the present invention, including data readers, data transmitters, data communicators, as well as data communication between a two components such as a display and an electric toothbrush.

A data reader can be associated with an electric toothbrush in variety of ways. For example, the data reader can be provided in the toothbrush handle, a charging station, a detached display or other detached device, a toothbrush stand, etc. In one embodiment, a data transmitter can be provided as a radio frequency identification (RFID) tag that can be used to transmit data between the personal care product and the display 45. As known in the art, an RFID tag comprises an electronic chip that contains encoded information and an antenna that transmits and/or receives information or data (including information stored by the chip) using radio waves. A reader is used to decode the data transmitted from the RFID tag. The RFID tag may be provided without an internal power supply, and the minute electrical current induced in the antenna by the incoming radio frequency signal from the reader provides just enough power for the integrated circuit in the tag to power up and transmit a response to the reader. The RFID tag can be a read only tag or a read/write tag. The data stored by a read only tag is pre-programmed, typically by a manufacturer, in non-volatile memory and cannot be changed by a later user of the personal care product or system. The data stored by a read/write tag can be later rewritten to the tag during later use, typically by the reader.

The data stored by the RFID tag or other data transmitters/communicators can be quite varied, including any personal care information. Some of the categories of data includes product identification data (e.g., the brand name or product name) and product usage or regimen data (e.g., usage time, such as 1 minute regimen for a rinse, text or graphical instructions concerning product usage), one or more rewards, and component or product replacement data (e.g., number of times or length of time that a component or product can be used before it should be replaced). Instructional images, text, or data can be particularly useful for children in establishing appropriate brushing regimens. Data can be directly displayed on the display 45 or can be used as an input to the processor 62 (FIG. 4) for a function or feature of the display 45. For example, an RFID tag 199 for the rinse product 170 could store usage data that states the recommended usage time for the product is 1 minute. The RFID tag can transmit the usage data to a reader 201 associated with the display 45. The usage data can be used as an input for a count-up or count-down timer (e.g., 130 in FIG. 7) that is then set to one minute. To initiate the data transmission from the RFID tag 199 to the reader 201, the product containing the RFID tag 199 need only be placed in sufficient proximity to the reader 201 to power-up the RFID tag.

The RFID tag can be embedded within or attached to the packaging of a personal care product, such as the rinse bottle 203 or the dentifrice tube 205. The RFID tag 199 might also be attached to or embedded within the product itself where possible. For instance, the RFID tag might be embedded or attached to the handle 207 of the manual toothbrush 180.

The data communication between a data communicator and a data reader can occur at a variety time before, during, or after an oral-care regimen and can be sequential or modulated. For instance, each of a plurality of oral-care products having an RFID tag might be moved in proximity of the display 45 so that the RFID tag can transmit its data to a reader 201 that is part of the display 45, the sleeve 60, or another component of one of the personal care systems. The data transmission can occur prior to each usage of the oral-care product or may only need to occur once, such as the first time the product is used, and the data is thereafter stored by the reader 201 (or the memory 64) or a component associated with the reader 201. A counter can be implemented that stores the number of times that data is transmitted from the RFID tag to the reader 201 for each personal care product.

In one method of the present invention, the manual toothbrush 180 having an RFID tag 199 can be moved near the display 45 having the reader 201 to transmit identification, usage information, and replacement information to the reader 201. The identification data can comprise the name of the product, and the usage data can comprise the recommended usage time (e.g., 2 minutes per brushing cycle). The replacement data can comprise the number of times that the manual toothbrush can be used before it should be replaced. Replacement may be desirable if the bristles have degraded sufficiently to affect the cleaning performance of the toothbrush. The reader 201 reads the transmitted data and the display 45 displays the name of the product and initiates a 2 minute timer for a brushing regimen. Each time the manual toothbrush 180 transmits data to the reader 201, a counter implemented by the processor 62 increments by one. Once the counter reaches the value of the replacement data, the display 45 can display an image, text, or other signal that the manual toothbrush 180 (or any replaceable component of other products) should be replaced. If the display is in data communication with a computer network, a replacement product could automatically be ordered for the user. The manual toothbrush 180 might also be moved in reading proximity of the reader 201 at the end of the brushing cycle, wherein the second data transmission to the reader within a predetermined period of time (e.g., 5 minutes) can be used to indicate the termination of the brushing cycle by the user. The reader 201, or components associated therewith, can be programmed to analyze the start and stop points of a plurality of brushing cycles and to display helpful feedback to the user of the personal-care products and/or systems. For instance, average brushing times/dates might be displayed. The analytical data might be displayed at predetermined times according to a calendar function associated with display 45 (e.g., once a week). Next, the user might move the rinse package 203 near the display 45 to transmit its data to the reader 201 after which the display 45 could display the product identification data and initiate a timer for use of the rinse by the user. Likewise, the packaged tooth whitening product 183 can be moved near the display 45 to transmit its data to the reader 201 after which the display 45 could display the product identification date and initiate a timer for the length of use of the tooth whitening product by the user (e.g., 5, 10, 15, 20, 25, or 30 minutes). Reminders for future use of the packaged tooth whitening product 183, or other product, could also be displayed based upon a calendar function or analysis of the oral-care regimen data.

One or more of the personal-care products, displays, devices, and/or system components described herein can be bundled together for distribution to a user as a kit. For example, a packaged dentifrice product, a manual toothbrush product, and a packaged rinse product in combination with a display capable of communicating with each of these products can be provided as a kit.

In another embodiment, one or more oral-care products can communicate directly with the electric toothbrush and/or its base. Referring to FIG. 14, a system 30 comprising a plurality of oral-care products 35, 170 and 175 is illustrated. The oral-care product 170 is illustrated as a packaged oral-care rinse product and the oral-care product 175 is illustrated as a packaged dentifrice product. The oral-care products 170 and 175 can communicate using data links 191 and 193 with the electric toothbrush 35 and/or its base 40. While certain products have been shown for ease of discussion, it will be understood that a variety of other products and personal care systems can be substituted. The data links can be wireless or via signal lines as previously discussed. The system 30 and products 35, 170, and 175 may also be connected to a network 161 via a data link 163, as previously described.

The system 30 can incorporate one or more of the electrical components previously described and illustrated in FIG. 4. In one embodiment, the electrical components are incorporated in the electric toothbrush 35 and/or the base 40. In another embodiment, the electrical components are incorporated in the handle 100 of the electric toothbrush 35. The oral-care products 170 and 175 can each incorporate one or more data communicators 199. The data communicators can be provided in any form, including but not limited to an RFID tag, a bar code, a shot code (e.g., an arrangement of black and white blocks which can be detected), or a magnet as previously described. A reader 201 may be located on the base 40, as shown in FIG. 14, or may be associated with the electric toothbrush 35. The reader 201 is capable of data communication with the data communicators 170 and 175. The data that may be transmitted by the data communicators and/or detected or received by the reader is varied and can be any of the information previously described.

In one example, the data communication includes data concerning the type of dentifrice or rinse that is part of the packaged products 170 and 175. With regard to the packaged dentifrice product 175, the data can include a code or description of the dentifrice or its ingredients, such as a sensitivity dentifrice, polishing dentifrice, light activated dentifrice, whitening dentifrice, etc. The data may be processed by the one or more processors 62 to determine, modify, change, implement, control, activate, initiate, and/or set one or more characteristics of the electric toothbrush 35. The characteristics of the electric toothbrush 35 can be quite varied and may include any of the characteristics previously described.

In one embodiment, the characteristic may include the bristle field configuration, which may be adapted or changed as a result of the processing of data communicated by the data transmitter to the reader, which is then communicated to the processor 62. Referring to FIGS. 15, 16, and 17, an electric toothbrush 35 is illustrated whose bristle field configuration may be changed as a result of processing data from a data transmitter or communicator. The toothbrush 35 comprises a head 220 and an outer bristle field 222 and an inner bristle field 224. Additional bristle fields may also be provided. The outer bristle field 222 may extend from a fixed component 226, and the inner bristle field 224 may extend from a movable component 228. In some embodiments, the auxiliary bristle field 226 may extend from the fixed component 226 and/or the movable component 228.

An actuator assembly 230 can be disposed within a cavity 232 of the handle 233 of the electric toothbrush 35. In some embodiments, the actuator assembly 230 includes a power source 234, a first motor 236, a second motor 238, and a drive system 239. The power source 234 is schematically depicted to include, for example, a battery such as a AA or AAA battery. The first motor 236 may include an electric motor powered by the battery and may include an output shaft 240 (shown in FIG. 16). The second motor 238 may include an electric motor, which may also be powered by the battery, having an output shaft 242 and an eccentric weight 244.

The drive system 230 may operably couple the first motor 236 to the movable component 228 of the head 220. The first motor 236 may operate as a conventional rotary motor to spin the output shaft 240 and drive the drive system 230. The second motor 238 may also include a conventional rotary motor; however, upon actuation, the eccentric weight 244, which is attached to the output shaft 242, may cause the toothbrush to vibrate similarly to the Oral-B Pulsar™ toothbrush that is commercially available from The Procter & Gamble Company and described in U.S. Pat. No. 6,564,416 and 2005/0235439. Additionally, embodiments are contemplated where a user may select between actuation of either or both of the motors 236, 238. In some embodiments, the motors 236, 238 may work in conjunction with each other, and/or independently of one another.

With continued reference to FIG. 15, as well as FIG. 16, the handle 234, the fixed component 226, and the movable component 228 may be separate components. These components may be formed separately and subsequently assembled. As mentioned above, the handle 234 may include a cavity 232 containing the actuator assembly 230. In the depicted form of the handle 234, the cavity 232 is complexly shaped to securely accommodate each of the components of the actuator assembly 230, as well as a portion of the fixed component 226 of the head 220. However, in an alternate form, the cavity 232 may be uniformly shaped and the components of the actuator assembly 230 may be fixed therein with an adhesive or some other device. In still another form, the fixed component 226 of the head 220 and handle 234 may be formed of a single piece or separate pieces.

During operation, the power source 234, for example a battery, may provide electrical energy to the first motor 236. The output shaft 240 of the first motor 236 may then effect a rotation of a drive cam 248. As the drive cam 248 rotates, a flange 250 rotates and the inclined surfaces 252, 254 continuously slidably engage bosses 256 on linear follower link 258. This sliding engagement converts the rotational motion of the first motor 236 into linear displacement of the linear follower link 258. The linear follower link 258 thus drives the articulation link 260 and finally, the movable component 228.

Referring to FIG. 17, the movable component 228 is illustrated in a first position, which defines a first configuration for the bristle field(s) of the head 220 of the toothbrush 35. In this position, the axially forward portion 262 of the flange 250 of the drive cam engages the bosses 256 on the linear follower link So configured, the linear follower link 258 is disposed in its left-most position relative to the orientation of FIG. 17. Consequently, the articulation link 260 is disposed in its left-most position. Additionally, the movable component 228 of the head 220 is disposed in its left-most and upward-most position relative to the fixed component 226. So positioned, the outer bristle field 222 and the inner bristle field 224 are generally aligned in height. Said another way, the outer bristle field 222 terminates at a first plane, which is identified by reference numeral 266 in FIG. 17, while the inner bristle field 224 terminates at a second plane, which is identified by reference numeral 268 in FIG. 17. In the first configuration, the first and second planes 266, 268 are generally the same plane. Thus, FIG. 18 depicts the bristles of the toothbrush 35 including the outer bristle field 222 and the inner bristle field 224 defining a first configuration of the head 220.

In this first configuration, the outer bristle field 222 is adapted to perform a first cleaning operation, while the inner bristle field 224 is adapted to perform a second cleaning operation. The first and second cleaning operations may generally identical, but direction dependent, or may not be generally identical. The first and second cleaning operations may include a surface cleaning operation, as well as an interproximal cleaning operation.

As the first motor 236 rotates the drive cam 248 to the second position indicated in FIG. 18, which defines a second configuration for the head 220 of the toothbrush 35, the axially rearward portion 284 of the flange 250 becomes disposed between the bosses 256 on the linear follower link 258. So configured, the linear follower link 258 is disposed in its right-most position, relative to the orientation of FIGS. 17. Consequently, the articulation link 260 is disposed in its right-most position. Finally, the movable component 228 of the head 220 is disposed in its right-most and downward-most position relative to the fixed component 226. In this second position, the outer bristle field 222 extends a predetermined distance beyond the inner bristle field 224. Said another way, while the outer bristle field 222 still terminates at the first plane 266, the inner bristle field 224 terminates at the plane 268. The plane 268 is generally parallel to and offset below the plane 266. In one form, the plane 268 is disposed approximately between about 0 to about 10 millimeters below the plane 266 or any individual number within the range. Thus, FIG. 18 depicts the bristles of the toothbrush 35 including the outer bristle field 222 and the inner bristle field 224 defining a second configuration of the head 220.

Therefore, it should be appreciated that as the first motor 236 rotates the drive cam 248, the drive cam 248 displaces the linear follower link 258, which in turn displaces the articulation link 260 and the movable component 228, in some embodiments. More specifically, as the drive cam 248 displaces the linear follower link 258 from the first position illustrated in FIG. 17 to the second position illustrated in FIG. 18, for example, the linear follower link 258 pulls the articulation link 260 and causes it to slightly rotate in the counterclockwise direction about pin 269. Additionally, in some embodiments, as the articulation link 260 pulls the movable component 228 from the first position illustrated in FIG. 17 to the second position illustrated in FIG. 18, the rearward surfaces 274 of the bosses 275 on the movable component 228 (see FIG. 16) slidably displace along the rearward surfaces 276 of the slots 278 in the fixed component 226. Accordingly, the opposite occurs when the drive cam 248 displaces the movable component 228 from the second position illustrated in FIG. 18 to the first position illustrated in FIG. 17. Specifically, as the drive cam 248 displaces the linear follower link 258 from the second position illustrated in FIG. 18 to the first position illustrated in FIG. 17, the linear follower link 258 may push the articulation link 260 and cause it to slightly rotate in the clockwise direction about pin 269. Additionally, as the articulation link 260 pushes the movable component 228 between the second position illustrated in FIG. 18 to the first position illustrated in FIG. 17, the forward surfaces 280 of the bosses 275 on the movable component 228 may slidably displace along the forward surfaces 282 of the slots 278 in the fixed component 226. Thus, during use, the actuator assembly 230 may displace the inner bristle field 224 between two heights and longitudinal positions relative to the outer bristle field 222 thereby defining the two configurations of the head 220 discussed above.

The actuation of the first motor 236 to move the movable component 228 between the first and second positions may be controlled by the processor 62 as a result of the analysis of the data communicated between the reader 201 and the data communicators 199. In other embodiments, the processor 62 may control, including variable control, the speed, frequency, and/or amplitude of one or more bristle carriers or bristle fields as a result of the analysis of data communicated between the reader 201 and the data communicators 199. For example, the processor 62 may control operation of the motor 234 to move the movable component 228 to the bristle configuration shown in FIG. 18 (a first configuration) when the data communicated to the processor 62 indicates, or has been analyzed to indicate that, the packaged dentifrice product 175 may provide a sensitivity benefit to a consumer. The bristle configuration shown in FIG. 18 may be configured to provide a sensitivity benefit, such as fewer bristles contacting the teeth resulting in a less aggressive tooth and gum feel, such that the first configuration provides the same, similar, and/or synergistic benefit with the dentifrice. The sensitivity benefit of the dentifrice may be provided by one or more ingredients or agents. An example of some ingredients which may be suitable is described in USPN 2002/0041852. The sensitivity benefit may be identified to the consumer by one or more images, phrases, or slogans associated with the packaged dentifrice product 175. The data that is communicated to the processor 62 may include an identifier that that the dentifrice has a sensitivity benefit or an identifier for one or more of the ingredients or agents of the dentifrice. In addition or alternatively, the processor 62 might control the operation of motor 238 so that the motor rotates at a speed that delivers a less aggressive movement or vibration (frequency and/or amplitude) to the head 220 and the bristles thereof. Other benefits that may be delivered by a dentifrice product, or other oral-care product, and which may have data, such as an identifier, that is communicated to the processor 62 include, whitening, polishing, malodor, anti-gingivitis, anti-cavity, anti-tartar, anti-erosion, and anti-plaque benefits as well as combinations thereof. The data that is communicated to the processor 62 from the dentifrice product 175 may identify one or more ingredients, agents or actives of the dentifrice, including but not limited to any of those described in U.S. Pat. No. 6,846,478; 6,740,311; 6,696,045; 2004/0126335; 2006/0171907; and 2003/0124065.
